On this graph, the red line & bar indicate the USB enclosure and the blue line & bar represent the Thermaltake Muse eSATA enclosure.  As you can see there is absolutely no competition between the two, the SATA enclosure completely dominates in every catagory.  The eSATA enclosure shows an increase of speed over the USB enclosure in random access time, average read speed, sequential read speed, and burst speed.  You may however notice that the burst speed, average read, and sequential read speed aren't that of what a true SATAII drive should produce.  Going back to earlier in the review where I had noted the lack of true SATAII cabling both on the PCI bracket and inside of the enclosure itself, this is where the problem lies.  If Thermaltake were to revamp the entire system using SATAII cables throughout we would more than likely be able to see a massive hike in performance.

These results are nothing to scoff at however.  The performance of this enclosure is unrivaled by any USB enclosure and is very economical as the price of SATA/SATAII drives are falling rapidly and can be found cheaper than IDE drives in some cases.
